Embodiment 1

[0065] (1) Raw materials: In terms of the weight of nylon 6 slices, weigh 1.0% of its weight PVP (PVP10000 and PVP24000 mass ratio is a mixture of 2: 1), 0.8% of MgSO 4 , 0.2% of antioxidant (antioxidant 1010 and antioxidant 168, the ratio of the two is 1:1), 0.2% of dispersant (liquid paraffin and PEG600, the ratio of the two is 1:1).

Embodiment 2

[0068] The vacuum-dried nylon 6 slices (moisture content 580ppm) and hygroscopic fine denier / ultrafine denier nylon masterbatch (moisture content 850ppm) are transported to the twin-screw high-speed spinning machine, and the supply volume of the nylon slice pump is 86.4g / min , the flow rate of the masterbatch pump is 1.32g / min, when the melt spinning temperature is 281°C, the screw speed is 25r / min and the screw pressure is 90-110kg / cm 2 Next, the molten mixture is extruded by a screw (including static and dynamic mixers), pumped into the spinneret assembly by metering, filtered by sea sand, and then passed through the spinneret hole (the spinneret hole is characterized by a diameter of 0.3mm, Aspect ratio 2.7) extrusion. Then, in the spinneret ring air blowing device, the temperature of the blown air is 36°C, the humidity is 50%, and the wind speed is 0.3m / s. Next, the fibers cooled by side blowing are bundled and oiled through an oil mist nozzle, and the oiling rate is 0.9 ...

Embodiment 3

[0070] (1) Raw materials: by weight of nylon 6 slices, weigh 2.4% of its weight PVP (the mixture of PVP10000 and PVP24000 with a mass ratio of 2:1), 3% of Zn(Ac) 2 , 0.5% of antioxidant (antioxidant 1010 and antioxidant 168, the ratio of the two is 1:1), 0.4% of dispersant (liquid paraffin and PEG600, the ratio of the two is 1:1).

Abstract

The invention belongs to the field of spinning materials, and firstly provides a hydroscopic fine denier / superfine denier chinlon master batch which is prepared by adding a hydroscopic modifier, a metallic salt, an antioxidant and other auxiliary agents into nylon 6 chips in proportion to perform melt blending and extrusion, wherein the hydroscopic modifier is PVP; the hydroscopic fine denier / superfine denier chinlon master batch is mixed with the nylon 6 chips to perform melt spinning in proportion, and hydroscopic fine denier / superfine denier chinlon POY filaments are prepared by further performing cooling, oiling bunching and winding on the hydroscopic fine denier / superfine denier chinlon master batch and the nylon 6 chips. The hydroscopic fine denier / superfine denier chinlon POY filaments have the filament number of 0.4 to 0.88 dtex, the breaking strength of 3.3 to 3.8 cN / dtex, the elongation at break of 60 to 120 percent and the fiber hydroscopicity of 4 to 10 percent, so the blank of producing the hydroscopic fine denier / superfine denier chinlon POY filaments by adopting a conventional spinning method at home and abroad is filled up, and simultaneously the improvement on the hydroscopicity of the chinlon POY filaments provides a wider application space for the chinlon POY filaments.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to a special masterbatch for hygroscopic fine denier / ultrafine denier nylon, a preparation method thereof, and hygroscopic fine denier / ultrafine denier nylon prepared therefrom. Background technique [0002] At present, synthetic fibers generally include polyester (polyethylene terephthalate), nylon (polyamide), polypropylene (polypropylene), spandex (polyurethane), acrylic (polyacrylonitrile) and the like. These fibers have different properties and thus different uses. But at present generally take fabric, because its fiber is thicker, feel rough, softness is poor, air permeability is poor, water absorption is poor, easy to pilling. With the improvement of people's living standards, the requirements for textiles are getting higher and higher. To solve these problems, meet people's different requirements, and develop different types, research on new and functional fib...
